MANILA, Philippines ? Some women have called up the Quezon City Police District headquarters in Camp Karingal to report that they or their daughter were also victimized by taxi driver Primitivo Sarmiento, who was arrested based on a tip on Monday after he robbed and attempted to abduct a University of Santo Tomas student last month.

Supt. Antonio Yarra, chief of the QCPD General Investigation section, said that four women have signified their intention to file charges against Sarmiento after they identified him through an artist sketch released by the police.

Two more have contacted lawyer Mon Pangarigan to say that they were also victimized by the suspect.

Pangarigan represents Valerie (not her real name), the 18-year-old UST student who boarded Sarmiento?s KUL taxicab with license plate TWC 897 on Nov. 22.

In her complaint, Valerie accused the driver of taking her P1,000 bill. She also claimed that when she insisted on getting her change, Sarmiento sped off with her still inside the cab. She escaped by jumping from the running vehicle, sustaining minor injuries in the process.

Following his arrest, Sarmiento was charged by the QCPD Criminal Investigation and Detection Unit with estafa and kidnapping at the Quezon City Prosecutor?s Office.

The charges were approved by First City Prosecutor Meynard Bautista who recommended no bail for the suspect?s temporary liberty.

Tuesday, a staffer of Land Transportation Office chief Alberto Suansing who identified himself as Cesar Aguila went to the QCPD headquarters to investigate Sarmiento for the possible permanent cancellation of his driver?s license.

Pangarigan told the Inquirer that the suspect used the same modus operandi to rob his victims, mostly young students, although he did not try to abduct them like he did with Valerie.

Ironically, one of the incidents took place on Nov. 25, three days after Valerie was robbed and nearly kidnapped.

Tuesday, another woman who said she was victimized by Sarmiento narrated her ordeal in an e-mail she sent to the Inquirer.

Jane (not her real name) said that she boarded a KUL taxi cab with plate number TWC 897 at around 8:40 p.m. on Nov. 13.

She claimed that Sarmiento harassed her into paying him a fare of P1,250 by claiming that his taxi was an airport-accredited cab and therefore authorized to charge a higher metered fare.

Jane narrated that she flagged down the taxi on Mindanao Avenue and told its driver ? whom she later identified as Sarmiento based on TV news reports ? to bring her to her destination.

She added that the driver first stopped at an LPG refilling station a few blocks away and then drove toward Muñoz. After a few minutes, however, he stopped the cab and informed her that the fare was already P1,250.

The driver said that if he were to take her to her destination, her fare would reach P4,000.

When she protested, the driver angrily told her to get out of the vehicle but demanded that she pay the fare first.

?No one was nearby so I had no choice. I felt that he would [step on the gas] or announce a holdup so I [gave him] the money,? the victim said, adding that she immediately got out of the taxi cab afterward.
